I can't be certain what khloto meant, but reading their comment I envisioned them meaning connect with a founder of another company that the new startup team (like the op) would mutually "vibe with." I imagined that other founder to maybe have already raised money before and could mentor you a bit, but that really the hope is that you just keep meeting other founders and some of these relationships could go different ways, some stay mentoring, some become customers, some become partners in some promotional initiative. Basically I interpreted khloto to be nudgding a first time startup entrepreneur to take the first step to a mini yc of their own doing (i.e. build business relationships with other founders that go beyond just schmoozing and networking, and doing it with a three month or so timeline to start).
Networking is a king, and depending on what kind of exit OP envisions, they will need those contacts.
One way to get them is definitely going through an accelerator (YC), but this process is time-consuming and might not be worth it unless the startup is in early stages (just my opinion!).
The other one is just reaching out to other founders who went through similar situation or are planning to.
Again, all is subjective and deeply personal to what kind of startup do you want to run and what is your dream scenario. No advice will answer your question, as they require context and dialog.
A Good VC will listen and connect you with other founders, even before raising, but especially after.
